Precision Soil Management combines a number of different digital databases with field verification to generate the most highly accurate soil management zones in the business. Because of these highly accurate soil management zones the soil test results and soil fertility recommendations for each soil management zone are very precise.
Our unique process is based on actual soil, not an approximation of the soil from satellite data; a field attribute or a soil property. We have developed a proprietary system that allows us to tell you exactly what’s happening in your field, why and what to do.
If your fields have variability, Precision Soil Management can delineate it accurately and develop a prescription that will help you maximize profit for a crop in that field.
Step 1: Mapping the Soil Management Zones
Using a combination of high resolution aerial imagery, satellite imagery, yield maps and/or elevation maps as a guide, we begin the process of delineating the Soil Management Zones. We will go into a field and pull as many soil cores as necessary to determine what types of soil and how many soil types are in the field. A GPS receiver connected to our field computer keeps track of our precise location at all times so we can pull samples at the exact same locations in future years.
Step 2: Soil Analysis
After the soil management zones have been delineated out in the field, the samples are sent to a laboratory for complete soil analysis and the map is drawn. When the analysis is finished, PSM not only knows the different productivity areas (high, medium, low) within the field, but also the soil properties controlling or limiting crop productivity, such as salinity, high alkalinity, claypan layer, topsoil thickness, wetness, soil texture, etc. This data is then loaded into our proprietary system, were the initial yield goals for each zone, based on the crop, soil type and county are set. We then upload it to our secure website, where the information on the field can be viewed and edited by the customer.
Step 3: Writing the Prescription
After the yield goals and fertilizer options have been finalized, we sit down with the customer on-site to write the seeding and/or fertilizing prescriptions for the field. We will use the customer’s computer and software, or our own depending upon the situation. This prescription data then is loaded onto the ag equipment’s data card which will precisely control the seeding and fertilizer application rates in real-time.
